The mechanism of injury that results in peroneal tendon subluxation is as for an ankle sprain. However with a subluxing peroneal tendon the chance of the resultant instability and secondary pain settling with conservative management is far less than with an ankle sprain. In other words once the tendons have subluxed this tends to continue, irrespective of conservative management.
Most patients will demonstrate their subluxation without being asked but on occasion it can be subtle and require careful dynamic ultrasound assessment of the peroneal tendons during ankle circumduction.
With appropriate surgery and rehabilitation post-operative recurrence is rare.
